High voltage capacitor bank versus Watermelon

Razor says...

>> ^deathcow:
Notice the holes are pre-drilled. Do you think they pumped that melon full of something combustible? I guess they are pretty wet inside (I've never American Pie'd one or anything.)


I'd take the guess that such a large amount of direct current caused the water in the watermelon to decompose rapidly to hydrogen and oxygen. Both would expand rapidly, being partial cause to the explosion as pressure inside increased. Additionally, the combination of gases is highly combustible, and any spark generated between the electrodes would be enough to cause them to ignite, causing an additional pressure increase and explosion.

Honestly, I have no idea what you’re talking about here, as much of it seems to bear nothing even close to what I wrote. Maybe you didn’t read my post, or perhaps I didn’t make my self clear. Let me try again. The idea that democracy and science don’t work well together is simply not born out by the existing facts. If democracy and science don’t work well together, then how do we account for the disproportionate number of patents awarded to scientists working in democratic societies, the overwhelming number of advances in science made in the last hundred plus years by Americans and/or people living here under a democratic system? You don’t see how science and democracies are compatible? Fine. I’m just pointing out that there is no evidence for this claim, if anything there is a wealth of proof showing the opposite.

I listed the “intellectuals/scientists of the past” simply to point out that these egghead elites have done great work and done tremendous good in raising America’s prestige the world over.

As far as “intellectuals/scientists of the past who would be pretty upset about modern day America's current situation.” Unless you are in possession of a flux capacitor, assigning the thoughts on present day situations to people that have long been dead and were the product of a far different time and environment is a foolish endeavor. (I will concede however that Thomas Jefferson would most likely be mortified to learn that thanks to science, and a science he helped pioneer, future generations uncovered his little secret regarding Sally Hemmings) I’m sure that some of the founding fathers did not want to give political power to the common man. But I suspect they may have been the same people that had no issue with owning slaves, or treating women as second class citizens, so what they thought then bears little relevance to what we have now.

As far as your claim that so many scientists were communists, your post listed only two. How does two translate to “so many” in a vocation that has millions the world over? Additionally, as the Communist Manifesto was published only 150 years ago, and men have been practicing science for centuries, the idea that “so many scientists of the past supported Communism” is to put it kindly, a little hard to swallow. Considering how much scientists and researchers depend on the free market system to fund their work, I would hazard to guess they would be more interested in living under that system than not.

In regards to “There's nothing about democracy that requires free speech, and free speech does not require democracy.” I really have no clue as to how this relates to anything I posted, or where you felt such a statement fit in to the overall argument.

Have you tried adjusting the flux capacitor with a nadion pulse? That should fix it right up.

In reply to this comment by soulmonarch:
Apologies, sir.

...My Heisenberg compensator was obviously malfunctioning. >_>

In reply to this comment by gwiz665:
Way to break my joke.

In reply to this comment by soulmonarch:
For what it's worth: Black holes very well MAY work that way, at least in relation to tachyons.

A tachyon is a theoretical particle that has no mass, and may therefore exceed the speed of light (or possibly escape a black hole.) That's why you always hear them used in relation to black holes, gravity anomalies and FTL travel.

*shrug* So what if tachyons may not exist? That's part of the fun of fiction.

>> ^gwiz665:
BLACK HOLES DO NOT WORK THAT WAY! GOOD NIGHT!
>> ^Ornthoron:
He left out the episode where they are trapped inside a black hole, and use a tachyon beam as a crowbar to force a hole in the event horizon so they can get out.

how to do the cell phone popcorn hoax

burdturgler says...

Like I said here ... it is very dangerous (as in lethal / deadly) to touch anything inside your microwave (even if it's unplugged) if you do not know what you're doing. The high voltage capacitor still has the capacity to kill you if it's not discharged even if the microwave isn't plugged in.

The Memristor Will Replace RAM and the Hard Drive

westy says...

Memristors /memˈrɪstɚ/ ("memory resistors") are a class of passive two-terminal circuit elements that maintain a functional relationship between the time integrals of current and voltage. This results in resistance varying according to the device's memristance function. Specifically engineered memristors provide controllable resistance useful for switching current. The memristor is a special case in so-called "memristive systems", a class of mathematical models useful for certain empirically observed phenomena, such as the firing of neurons.[3] The definition of the memristor is based solely on fundamental circuit variables, similar to the resistor, capacitor, and inductor. Unlike those more familiar elements, the necessarily nonlinear memristors may be described by any of a variety of time-varying functions. As a result, memristors do not belong to linear time-invariant (LTI) circuit models. A linear time-invariant memristor is simply a conventional resistor.[4]

Memristor theory was formulated and named by Leon Chua in a 1971 paper. Chua strongly believed that a fourth device existed to provide conceptual symmetry with the resistor, inductor, and capacitor. This symmetry follows from the description of basic passive circuit elements as defined by a relation between two of the four fundamental circuit variables, namely voltage, current, charge and flux.[5] A device linking charge and flux (themselves defined as time integrals of current and voltage), which would be the memristor, was still hypothetical at the time. He did acknowledge that other scientists had already used fixed nonlinear flux-charge relationships.[6] However, it would not be until thirty-seven years later, on April 30, 2008, that a team at HP Labs led by the scientist R. Stanley Williams would announce the discovery of a switching memristor. Based on a thin film of titanium dioxide, it has been presented as an approximately ideal device.[7][8][9] Being much simpler than currently popular MOSFET switches and also able to implement one bit of non-volatile memory in a single device, memristors integrated with transistors may enable nanoscale computer technology. Chua also speculates that they may be useful in the construction of artificial neural networks.[10]

Noisy Youths Sentenced To Listen To Barry Manilow & Barney

1. Your band sucks, never play outside of the garage. Better yet, sell the instruments to buy food for needy families this holiday season.

2. I know your Pioneer 6X9's are "cool", especially coming off your factory head unit, but I don't want to hear your Kanye West played with 10% distortion and no midrange. Keep your (c)rap to yourself.

3. If you spent more on your 2 12" subs, amp, receiver, capacitor, wiring kit, and component 6 1/2's than your 1992 Corolla is worth, please leave the country, and never come back. Thank you.

So . . . what makes a hard drive light on fire? (Wtf Talk Post)

How the Cell Phone + Popcorn Trick Really Works

joedirt says...

I personally think everyone watching this should flag it on YT.
THis is the most dangerous video I've ever seen. You know how many people will try this?? First of all, isn't the magnetron leads also connected to some very large high-voltage capacitors? I'm pretty sure those will kill you with two handed discharge. (You;re probably ok poking around with one hand).

Also microwaves are very dangerous. Aren't most of the studies coming out now showing the cell phones cause DNA damage to children. It might not be ionizing, but I'm pretty sure it wrecks DNA, unless it is too tuned to vibrating water, and hence all the water absorbs all the energy.

Anyways, for sure all the idiots around the table watching it would have their eyes cook. Also the energy falls off as 1/distance^3

For anyone contemplating digging around inside their microwaves, be aware you can receive a lethal shock even when it's unplugged because of it's high voltage capacitor. Very irresponsible for whoever made this to leave that out.


Darwin works his magic.
Anyone willing to do this without knowledge of electrics, and a radiation shield...well I say go for it.
Its about time we had a mass exodus of stupid from the gene pool.
